静电集尘分为三个阶段：颗粒物荷电、沉积和清灰。（1）在放电极与集尘极之间加高电压，使放电极发生电晕放电，气体电离，生成大量的自由电子和正离子。对于负电晕，在放电极附近的电晕区内正离子立即被电晕极吸引而失去电荷。自由电子和形成的负离子则因受电场力的驱使向集尘极移动，并充满到两极间的大部分空间。含尘气流通过电场空间使自由电子、负离子与粉尘碰撞并附着其上，实现粉尘的荷电。（2）荷电粉尘在电场力中受库仑力的作用被驱往集尘极，到达集尘极表面后放出所带电荷并沉积其上。（3）集尘极表面的粉尘沉积到一定厚度后，应蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 将其清除。而放电极也会附着少量粉尘，隔一段时间也需要进行清理。
Electrostatic dust collection can be divided into three stages: particle charging, deposition and ash removal. (1) A high voltage is applied between the discharge electrode and the dust collector to make the discharge electrode generate corona discharge, gas ionization, and a large number of free electrons and positive ions. For the negative corona, the positive ions in the corona region near the discharge electrode are immediately attracted by the corona electrode and lose their charge. The free electrons and the formed negative ions move to the dust collecting pole driven by the electric field force and fill most of the space between the two poles. Through the electric field space, the dusty air stream makes free electrons and negative ions collide with dust and attach to it, so as to realize the charging of dust. (2) The charged dust is driven to the dust collector by Coulomb force in the electric field force, and then it reaches the surface of the dust collector to release the charge and deposit it. (3) The dust on the surface of dust collecting pole shall be removed after it is deposited to a certain thickness. The discharge electrode will also attach a small amount of dust, which needs to be cleaned up after a period of time.
